Nothing makes an impression like moving pictures with sound. That's why digital video continues to grow in importance online. Couple that trend with the ever-increasing availability of devices capable of high-resolution video recording—smartphones, GoPros, DSLRs—and the case for ever-more powerful video editing software becomes clear. Further, the software must be usable by nonprofessionals, and it has to keep up with newer formats such as HEVC (High Efficiency Video Coding) and 360-degree VR video. It also must be able to let you work with 4K video, since common devices are now capable of producing 4K content.
Openshot is entirely open source, which makes it one of the best video editing software that is accessible. It may remind some Mac users a little of iMovie with its easy to use drag and drop interface. However, Openshot packs more features than iMovie, including unlimited layers and audio mixing. This free editor strikes a nice balance between advanced features and a simple interface. It also allows real-time previews when you create transitions between clips.
In terms of usability, Camtasia should be among the top choices due to how beginner-friendly it is. But, also due to its simplicity, not too many professional creators will find Camtasia Studio appealing. If you’re only starting to learn the basics of video editing, this app is perfect for that. It’s got a nice interface, intuitive controls, and useful tutorials. Those are everything you need for an easy beginning. 
ZS4 Video Editor is another video editor for Mac just like Avidemux. It's an open source software create by combined efforts of many users like you. It was first published in 2012 as a beta project. Today, ZS4 Video Editor is best known for taking into consideration the basic needs of an average MacBook user and streamline it to fit those requirements.
Spark Video comes pre-loaded with themes that control the overall look and feel of your video. Themes power transition effects between slides, allowing for logo reveals and logo animations. Simply tap the “Themes” category and choose from tk unique themes. You can also add music by uploading your own track or selecting one of the free songs in Spark Video.

When you’re doing a tutorial or game session, and you want the audience to see your expressions, CS can help with that. Use the picture-in-picture mode to create a video showing your instructions on screen. Another cool thing when using this is that Camtasia can split the recorded file into two separate tracks. One for your talking head and one is the actual content. You can edit each of them as an entire project.

Smooth functioning: Camtasia provides a lot of nice features in a fluid interface that makes creating screen capture videos and processing them a breeze. You can set the program to record either the screen or a PowerPoint presentation. You can also choose to record your entire screen or only a portion of it that you preset before recording begins. The recordings, themselves, are clear and crisp, providing you with an excellent framework on which to put all the finishing touches and effects you want.
